Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a reverse osmosis membrane component capable of relieving water pressure shock. Background Art

[0002] Reverse osmosis membrane assembly is a combination of reverse osmosis membrane, membrane support and container according to certain technical requirements. It is the smallest unit that can put the membrane into practical application. The finished membrane has sheet, tubular and hollow fiber shapes, and can be made into roll, plate, tubular and hollow fiber reverse osmosis membrane assemblies accordingly. Rolled membrane elements have specifications such as 2.5in, 4in, and 8in. Generally, 4in and 8in membrane elements are commonly used. In industrial water treatment, 8in membrane elements are the most commonly used.

[0003] When the reverse osmosis membrane in the prior art is in use, it is unable to block the particulate impurities in the water outside when the water source initially enters the reverse osmosis membrane assembly, thereby causing larger particulate impurities to enter the filter assembly inside the reverse osmosis membrane assembly, resulting in a relatively short service life of the internal filter assembly. To address the above problem, a reverse osmosis membrane assembly that can alleviate water pressure shock is provided. Utility Model Content

[0004] The utility model aims to provide a reverse osmosis membrane assembly capable of alleviating water pressure shock, so as to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, the clamping assembly includes a mounting sleeve, a return spring, a movable connecting plate, a connecting column and a curved clamping column. The inner wall of the accommodating groove is fixedly mounted with a mounting sleeve, the inner wall of the mounting sleeve is fixedly mounted with a return spring, one end of the return spring is fixedly mounted with a movable connecting plate, the movable connecting plate is slidably connected to the mounting sleeve, one side of the movable connecting plate is fixedly mounted with a connecting column, one end of the connecting column is fixedly mounted with a curved clamping column, the curved clamping column is slidably connected to the inner wall of the first membrane element end plate, and the curved clamping column extends to the interior of the mounting slot through the inner wall of the first membrane element end plate.

[0009] Furthermore, the protective component includes a mounting ring, a force-assisted disassembly groove, a filter, a clamping groove, a first arc surface and a second arc surface. The mounting ring is arranged inside the mounting groove. The outer surface of the mounting ring is provided with a force-assisted disassembly groove, and the number of the force-assisted disassembly grooves is fixed at two. The inner wall of the mounting ring is fixedly provided with a filter. The inner wall of the mounting ring is provided with a clamping groove, and the number of the clamping grooves is fixed at two. The clamping groove is clamped with a curved clamping column.

[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model uses a protective component in the end plate of the first membrane element, wherein the filter screen can effectively block larger particulate impurities and prevent them from entering the filter component. At the same time, the clamping component is clamped with the clamping groove of the protective component through the arc clamping column, thereby ensuring the stable installation of the protective component. When the protective component needs to be replaced, the mounting ring is pulled by leveraging the disassembly groove to pull the mounting ring upward. The mounting ring moves upward to make the arc clamping column contact the first arc surface, so that the arc clamping column squeezes the connecting column and the movable connecting plate, thereby squeezing and contracting the reset spring. The movable connecting plate contracts, thereby driving the connecting column and the arc clamping column to contract, thereby contacting the arc clamping column and the clamping groove, and the protective component can be removed. While increasing the service life of the filter component, it also achieves the effect of convenient and quick installation and disassembly.
